= Application filed May 8- 1907. Serial No. 372511- T 0 all whom it mayconcern: I

Be it known that I, J UDSON 000K, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inReinforced following to be a full, clear, and exact-description of theinvention, such as will enable .others skilled in the art to which itappertains to make and use same, reference being had to the accompanyingdrawings, and to the letters and figures of reference marked thereon,which form a part of this specification. This invention relates to newand useful improvements in brake shoes, and the object of the inventionis torproduce' a simple and efficient device of this nature comprisingessentially a shoe having a cast metallic body and a forged steel blankreinforcement embedded in the body and provided with truss ribs for thepurpose of strengthening and stiffening the shoe. My invention comprisesvarious details of construction and combinations and arrangearts whichwill be hereinafter in the appended claims. 7

I illustrate my invention in the accompanying drawings, in which Figure1 is a top plan view of the brake shoe. Fig. 2 is a longitudinalsectional view taken on line 2-2 of Fig. 1. Fig. 3 is a cross sectionalview on line 3-3 of Fig. 1, and Fig. 4 is a top plan view of thereinforcing forged metallic plate or blank.

Reference now being had to the details of the drawings by letter, 'Adesignates a cast metallic body portion of the shoe and B designates .ablank or plate of. forged steel which is longitudinally slitted, as atC, forming reinforcing ribs. Said blank, a detail of which is showninFig. 4 ofthe drawings, is substantially H-shaped-in top plan view, thetwo longitudinal portions being provided with the parallel slitsdescribed and con nccted together by means of the strap 1) which isintegral with said parallel portion.

Said blank, after being bent in the form shown in Figs. .1 to 3,inclusive, is embedded in the body ortion, the inner marginaledges ofthe para lel portions of the plate being brought in contact with eachother, said strap B forming a loop, as shown clearly in I doherebydeclare the .loop,

set forth.

Fig. 3 of the drawings to receive a key for fastening the shoe to a suporting means,-

while the straps formed by s 'tting the blank are depressedand'surrounded by the metal ofthe cast body portion, thereby securelyanchoring the blank or plate to the upperat portion of the shoe. It willbe noted t Y the circumferentialedge ofjthe body portion in which saidplate is embeddeirprojects a slight distance above the up er s ace ofthe blank forming a rib which urther reinforces theshoe bys'ecurelyholding'the blank in place.

From the foregoing, it will-be noted that by the provision of a brakeshoe made in accordancewith my invention, the body portion will bethoroughly reinforced, strengthened and. stiffened by the peculiarmanner of incorporating the forged steel blank as shown and described. 1

What I claim to be new is 1. A reinforced brake shoe comprising a castmetallic body portion, a forged blank comprising two parallel portionswhich are connected together by a strap forming. a

loop, the edges of said parallel v ortions bein in contact with eachother and incorporate in said cast body portion, as set forth.

2. A reinforced brake shoe comprising a cast-metallic body portion, aforged blank comprising connected together by a strap forming a loop,the edges of saidparallel portions bein in contact with each other andincorporated in said east body portion, said blankbeing slittedlongitudinally forming straps over which portions of the cast bodyextend, as set forth. v

3. A reinforced brake shoe comprising a cast metallic body portion, aforged blank compri ing two parallel portions which are connectedtogether. by a strap forming a being in contact with each other andincorporated in said cast-body portion, said blank being slittedlongitudinally forming straps over which portions of the cast bodyextend, a portion of the body extending above the marginal edge of saidblank, as

two parallel portions which are the edges of said parallel portions 4. Areinforced brake shoe comprising a lel portions a distance in from theinner In testimony whereof I hereunto affix my edges thereof anddesigned to form a loop, signature in the presence of two witnesses.said blank being slitted longitudinally forrn- JUDSON COOK ing strapswhich are bent to receive portions of' the cast body, whereby thereinforcing Witnesses:
